TM31 Terminal Module
Description
The TM31 Terminal Module is a terminal extension board. The TM31 can be used to
increase the number of digital inputs/outputs. Analog inputs and outputs are also available
on the TM31.
Fire hazard due to overheating because of inadequate ventilation clearances
Insufficient ventilation clearances result in overheating with danger to persons as a result of
smoke and fire. This can also result in more downtimes and reduced service lives of the
Terminal Module.
• For this reason, it is imperative that you maintain the 50 mm clearances above and
below the Terminal Module.
